i am trying to make the character creation work on a C++ source(Hybrid's one) and i am having some troubles.
i suppose the sequence goes like this(?):
1-> client sends (valid, meaning acc and pass are ok) login request to server
2-> server check for a character being existent on that account
3-> if no character is created on the specified account, server sends sends back a MessagePacket with the message "NEW_ROLE"
4-> client then goes into the class selection screen, chooses name, class, gender and body type and sends the coresponding character creation packet to the server
5-> server creates the character and disconnects the player in order to re-log.
however, it seems that i get a garbage packet on step (4) instead of a valid one which causes the server to disconnect the client and discard the data. for whatever reason i cannot find the problem, hope you guys can help me.
